Dear Patty,
Get off the computer. Go on, unplug. Pick up that hoop. You know, the one with the yarn you so lovingly crocheted on to it. Now move those hips! Your knee doesn't hurt today, and the baby's asleep, you have no excuse. Besides, IT'S FUN!!
Hoop for twenty minutes, ten minutes each way, then do some yoga, be sure to stretch out your back and calves...
